Similar triangles
Similar triangles is an interactive experiment in Plane Geometry, a free simulation from StudyFi Lab that runs right in your browser.
Scaling a triangle by a factor k multiplies every side by k and the area by k²; the angles stay the same.
Try this: Drag the triangle or change k — compare the sides, the angles and the areas.
